方法：这项二次分析检查了随机分配到能量限制生活方式干预组或生活方式干预组加上有限的非营养密集食物和能量密集食物的参与者的数据（n= 183）。通过3次、24小时的饮食回顾计算每日摄入LED和HED食物的数量，并在0、6和18个月时测量人体测量值。多变量调整广义线性模型和重复测量混合线性模型研究了6个月LED和HED食物数量变化与ED、体重指数（BMI）变化以及6个月和18个月体重减轻百分比之间的关系。结果：在51.9岁的女性（58%）和白人（92%）参与者中，在能量限制饮食后，增加LED食物的数量或减少HED食物的数量与6个月和18个月的ED减少有关（β= - 0.25至- 0.38 kJ g-1(- 0.06至- 0.09 kcal g-1)， P< 0.001）。只有增加食用LED食品的数量与6个月和18个月的BMI降低（β= - 0.16至- 0.2 kg m-2， P< 0.05）和6个月的体重减轻百分比降低（β= - 0.5%， P< 0.05）有关。在6个月和18个月时，每天食用≥2个HED食物和每天食用小于6.6个LED食物的参与者比每天仅食用≥2个HED食物的参与者有更好的减肥结果。结论：尽管减少HED食品的数量或增加LED食品的消费量对ED的影响相似，但只有增加LED食品的数量与减肥有关。这提供了初步证据，表明用于减少饮食ED的方法可能会对减肥轨迹产生不同的影响。需要随机对照试验来为ED减肥建议提供依据。
Methods:This secondary analysis examined data from participants randomized to an energy-restricted lifestyle intervention or lifestyle intervention plus limited non-nutrient dense, energy-dense food variety (n= 183). Number of daily LED and HED foods consumed was calculated from three, 24-h dietary recalls and anthropometrics were measured at 0, 6 and 18 months. Multivariable-adjusted generalized linear models and repeated-measures mixed linear models examined associations between 6-month changes in number of LED and HED foods and changes in ED, body mass index (BMI), and percent weight loss at 6 and 18 months.Results:Among mostly female (58%), White (92%) participants aged 51.9 years following an energy-restricted diet, increasing number of LED foods or decreasing number of HED foods consumed was associated with 6-and 18-month reductions in ED (β=− 0.25 to− 0.38 kJ g–1 (− 0.06 to− 0.09 kcal g–1), P< 0.001). Only increasing number of LED foods consumed was associated with 6-and 18-month reductions in BMI (β=− 0.16 to− 0.2 kg m–2, P< 0.05) and 6-month reductions in percent weight loss (β=− 0.5%, P< 0.05). Participants consuming⩽ 2 HED foods per day and⩾ 6.6 LED foods per day experienced better weight loss outcomes at 6-and 18-month than participants only consuming⩽ 2 HED foods per day.Conclusion:Despite similar reductions in ED from reducing number of HED foods or increasing number of LED foods consumed, only increasing number of LED foods related to weight loss. This provides preliminary evidence that methods used to reduce dietary ED may differentially influence weight loss trajectories. Randomized controlled trials are needed to inform ED recommendations for weight loss.
